Another cohort of startups blown out of the water.

"But where's the moat, but where's the moat", cries the armchair engineer with a PhD in React.

Meanwhile OpenAI goes brr ...

How does this page not immediately address what I assume is everyone's first question?

Is this browser built on Chromium, or is it a completely fresh creation?

I have to assume that because they AREN'T highlighting it that it IS built on Chromium.

I suspect that whatever screen vision and window control API they're using is macOS only.

So openAI's answer to Perplexity's Comet. I'm afraid this will be the future, as these AI-browsers do truly bring value. But they open up the gate for a single Big Tech Winner that truly knows everything about you, and can even control everything on your behalf.

I really hope open-source Browsers like Firefox follow up soon with better alternatives, like on-device LLMs to counteract the "all in the cloud" LLM approach. Of course that would require top-tier ML engineers who mostly all are pay-captured by Big Tech.

Since it’s Mac only, it could be WebKit.

Definitely not a new browser engine.

That shouldn't be downvoted. Their pivot from model -> product company is one to watch with admiration and dread in equal measure.
